1896.] BOTANICAL SECTION MEETING. 233 



This collection contains a very large number of the ordinary 

 forms which any one is likely to meet in his study of the fresh-water 

 species, and as the dried specimens are all from the collection of the 

 Rev. Francis WoUe, one of the foremost American students of this 

 group of plants, the collection is exceedingly valuable for reference. 



The gift of Mr. Rafter forms the beginning of a collection of the 

 lower cryptogams, which it is hoped may be rapidly increased until 

 the Academy possesses a complete set of all the plants found within 

 the limits of Monroe county. 



An alphabetical list of the species represented is filed with the 

 collection. 



On motion of Mr. C. C. Laney, a vote of thanks was extended 

 to Mr. Rafter for his gift. 



Miss Mary E. Macauley read a paper entitled: 



NOTES ON SOME MONTANA PLANTS. 



The paper described the differences and resemblances between 

 the Montana flora and our own, and was illustrated by specimens 

 collected during a recent visit to that part of the United States. 



Miss Florence Beckwith read a paper entitled: 



WEEDS. * 



The paper described a number of pernicious plants which had 

 been introduced into this region, and called attention to the laws of the 

 State in regard to the extermination of the most troublesome. It 

 spoke particularly of the efforts that should be made to prevent the 

 spread of the so-called Russian Thistle, which is increasing so rapidly 

 in the western States that it has already become a great nuisance. 



The paper was discussed by Professor Fairchild, Mr. Charles H. 

 Potter and Professor Lattimore. 



The remainder of the evening was devoted to the examination of 

 the exhibits of the Section, consisting of the following: 



A collection of photographs of trees, by Mr. C. C. Laney ; 



A photograph of a " Primeval Elm", one of Rochester's most 

 ancient landmarks recently cut down because standing in the way of 

 progress, presented to the Academy by Mr. H. C. Heath, through 

 the kindness of Mr. H. K. Phinney; 



*This paper was published, in part, in the Rochester Democrat and Chronicle, May 27, 1896; 

 printed in full in Vick's Magazine, Sept., 1905.
